VAULT.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed October 13, 1906. Serial No. 338,697.

To all whom, it may concern.-

Be it known that I, WILLIAM H. HOLLAR, of Philadelphia, in the State ofPennsylvania, have invented certain new and useful Improvements inVaults, whereof the following is a specification, reference being had tothe accompanying drawings.

My invention relates particularly to means for ventilating duringbusiness hours vaultinclosures which are required to be hermeticallysealed at other times; and it is an object of my invention to providemeans for effecting such ventilation by connection with the ventilatingsystem of the building in which the vault is located without thenecessity of providing any opening in the vault other than is requiredfor access to the vault contents.

As hereinafter described, my invention comprises the provision of anauxiliary inclosure exterior to the vault and inclosing an openingordinarily required for access to the vaultfor instance, theemergency-doorwaysaid auxiliary inclosure being the terminal of apermanent duct connected with the ventilating system of the building,the port between said duct and said auxiliary inclosure being controlledby a valve or register and the arrangement being such that when theemergency-door is opened continuous pneumatic connection may beestablished therethrough between the interior of the vault and theexterior ventilating system, so that air may be supplied to or withdrawnfrom the vault in connection with said system without disturbing ormodifying the ordinary construction, arrangement, or operation of thevault.

I am aware that other systems have been proposed for effecting theventilation of vault-inclosures; but, as far as I am aware, they eitherrequire openings leading to the vault independently of the ordinaryopenings controlled by doors provided with looks, or they require theprovision of collapsible or removable pipes which extend through andobstruct the openings whereby access is had to the vault and which mustbe removed when it is desired to close the vault and re placed when itis desired to ventilate it. Therefore my present improvement isadvantageo us in that the ordinary system of ventilation of the buildingis not only extended to and made effective with respect to thevaultinclosure whenever the latter is opened for business, but the vaultmay be closed hermetically in the usual manner and by the usual meanswithout the necessity of removing or replacing any pneumaticconnections.

My invention comprises the various novel features of construction andarrangement hereinafter more definitely specified.

The accompanying drawing is a diagrammatic plan view of the rotunda of abankbuilding in which is located a vault-inclosure convenientlyembodying my improvement.

In said drawing, 1 is the wall of the rotunda, 2 the outer vestibulethereof, and 3 the corridor leading from the vestibule to the interiorof the rotunda through the doorways 4 and 5 and to the vault-inclosure 7through the doorway 8, provided with the outer door 9, vestibule 10, andinner doors 11 and 12.

The rotunda-chambers 14 are provided with booths 15 and 16, the latterhaving doorways 17, through which access may be had to the auxiliaryventilating-inclosure 20, which extends between the rear Wall 21 of thevault 7 and the wall 1 of the rotunda and is provided with the doorways23, having the doors 24 opening into the respective booths 16. Saidinclosure 20 is provided with the partition 26, having the doorway 27and door 28, so that the inner chamber 29 of said inclosure 20 may behermetically sealed by closure of the door 28 without preyenting accessbetween said booths 16 through the doorways 23 and chamber 30. Saidchamber 29 in closes the emergency-doorway 35, which latter is providedwith the emergency-door 36, in the rear wall 21 of the vault and is alsoconveniently provided with the vestibule 38, having the inner doors 39and 40, covered by the grill 41, having the door 42. Said chamber 29 isprovided with the port 45, communicating with the duct 46, which extendsin communication with the ventilating system of the building, and saidport may be provided with any convenient device for opening or closingit, such as a slat-register 47, valve, or slidable door. Although Iprefer to extend said duct 46 beneath the inclosure 20 and locate theport 45 in the floor thereof, it is to be understood that connection ofsaid inclosure with the ventilating system of the building may beeffected in any convenient manner. For instance, if. the ducts of theventilating system are arranged overhead connection may be madetherewith through the ceiling of the inclosure 20.

The arrangement above described may be utilized as follows: At othertimes than busi- IIC ness hours the vault-inclosure 7 is hermeticallysealed by the outer door 9 and the emergency-door 86. However, at thebeginning of business hours the outer door 9 and front vestibule-doors11 and 12 being opened, the emergency-door 36 and its vestibule-doors 39and 40 are likewise opened. Thereupon the register 47 in theventilating-chamber 29 may be opened, thus establishing communicationbetween the ventilating system of the building, comprising the duct 16,

r and the interior of the vault-inclosure 7,

so that air may be withdrawn through the front doorway 8 and theemergency-doorway 35, or air may be forced through said doorway in thereverse direction, with the effect of receiving the atmosphere in saidin closure 7, the direction of passage of the air being of coursedeterminable in accordance with whether the ventilating system is of theexhaust or plenum type.

It is also to be understood. that I do not desire to limit myself to theprovision of but a single port within the inclosure 20, as it may beprovided with both an inlet-port and an outlet port for connection witha ventilating system of the combined exhaust and plenum type. Moreover,it is to be understood that I do not desire to limit myself to theprecise details of construction and arrangement above described, asvarious modifications may be made therein without departing from thescope of the following claims.

I claim 1. The combination with a vault provided with a doorway, of adoor arranged to hermetically seal said doorway; an auxiliary inclosureexterior to said doorway; and, a

independently of said door, controlling said doorway in thevault-inclosure, substantially as set forth.

3. The combination with a vault provided with a doorway, of a pneumaticduct permanently located with respect to said vault and terminating in aport exterior thereto; an auxiliary inclosure, exterior to said vault,connecting said port with the doorway of said vault; and, a doorwayprovided with a door in said auxiliary inclosure, substantially as setforth.

1. The combination with a vault provided with a doorway, of a pneumaticduct permanently located with respect to said vault and terminating in aport exterior thereto; an auxiliary inclosure, exterior to said vault,connecting said port with the doorway of said vault; and, means in saidauxiliary inclosure arranged to control said port, independently of saidvault, substantially as set forth.

In testimony whereof I have hereunto signed my name, at Philadelphia,Pennsylvania, this 12th day of October, 1906.

WILLIAM H. HOLLAR.
